HEATING DEVICE.

Specification of Letters Patent.

Application filed October 30, 1909.

Patented Apr. 12, 1910.

Serial No. 525,470.

To all whom it may concern:

Be it known that I, WALTER E. Fnos'r, citizen of the United States, residing at Auburn, in the county of Androscoggin and State of Maine, have invented new and useful Improvements in Heating Devices, of which the following is a specification.

My invention re ates to. heating devices a designed for use over a gas or other fuel the utensil-support comparatively remote from the burner.

With the fore oing in view, the invention will be fully understood from the following description and claims when the same are read in connection with the drawings, accompanying and forming part of this specification, in which:

Figure 1 is a vertical section taken through the longitudinal center of my novel device, and showing the-burner in elevation. Fig. 2 is a transverse section taken in the plane indicated by the line 2--2 of Fig. 1,

v with the burner in elevation. Fig. 3 is a detail elevation of the end of the cover member remote from the burner with a portion broken away. Fig. 4 is a detail plan view of the end portion of the device that is remote from the burner.

Similar letters designate corresponding parts in all of the views of the drawings, referring to which:

A is a base.

B is a'burner carried by the base and adapted to be supplied through a pipe 0 with gas or other fuel, and D is the body section of my novel heating device, which is adapted to be supported by legs E or otherwise above the base. The said body member D is preferably formed of metal and comrises a bottom wall a, a vertical wall b rismg from the edges of the bottom wall, a flange 0 depending from the bottom wall, at a oint adjacent one end of the member, and a apted to surround the burner B, and a longitudinal channel-portion (1 depending from the bottom wall and extending from the inner side of the flange 0 toward the opposite end of the member and having its bottom inclined upward toward said end, as shown in Fig. l.

E is the cover member of the device, which is also preferably formed of metal suitable to the purpose, the said cover member comprises a top wall 6 in which are separated openings f and g, surrounded by upstanding flanges h and 2'; the said top Wall being designed to rest on the vertical wall b of the body member D, a marginal flange j depending from the top wall 6 and adapted to surround the body wall I) with a view to preventing grease reaching the interior of the body member, and a flange 70 depending from the top wall 6 and inclosing the two openings and g therein, and adapted, when the top wall 6 rests on the side wall I) of body member I), to bear snugly on the bottom wall a of said body member. It will also be observed by comparison of Figs. 1, 3 and 4 that the cover member E is provided in its top wall e and flan e i, at a point remote from the burner B, wit 1 an opening Z for the escape of products of combustion, and is also provided on its top wall with a depending grooved portion m which extends longitudi nally between the openin g and the adjacent end of the cover mem er and is open at its upper side. The inner end of the grooved portion m communicates with the space inclosed by the flange 70 of the cover member E, and hence it will be manifest that when the o ening Z is closed by a utensil that surroun s the flan e z, the groovedportion m will form an a equate escape for the heat and products of combustion and in that way maintain the draft necessary to assure the passage of heat and products of combustion from the burner B to and past the bottom of the utensil on the flange z. j

In the practical use of my novel heating device, utensils are placed above the o enings f and g, whereupon the utensil a ove the former openin will be directly heated by the burner, whlle heat and roducts of combustion from the burner will deflected to and ast the utensil above the opening g and will pass out of the device through the opening Z and grooved portion m.

Incidental to the operation of the device, it will be observed that the heat and prodnets of combustion will be confined within the flange 7c of the cover member E while en route between the burner B and the escape opening Z andgrooved portion m, and that the dead-air space F, formed between the flange 7c of the cover member E and the side wall I) of the body member D, will prevent the radiation of heat from the device.

It will be gathered from the foregoing that when the device is to be cleaned, the cover member E as a whole may be lifted from the body member D with a view of facilitating such operation.

' The construction herein illustrated and described constitutes the best practical embodiment of my invention that I have devised, but it is obvious that in the future practice of the invention such changes or modifications may be made as do not involve de arture from the scope of my invention as de ned in the claims appended.

Having described my invention, what I claim and desire to secure by Letters-Patent, is:

1. In a heating device, the combination with a suitably supported body member coming a top wall resting on the side wal of the body member and having spaced open ings and a depending marginal flange surrounding the side wall of the body member and also having a depending flange inclosing the said spaced openings; the said flange bearing on the bottom wall of the body member and inclosing the space within the assess de ending flange and the longitudinal channelportion of said bottom wall, and forming in conjunction with the side wall of the body member an air space, substantially as and for the purpose set forth.

2. In a heating device, the combination with a suitably supported body member comprising a bottom wall having a depending flange adapted to receive a burner and also having a longitudinal channel portion communicating at one end with the space within said flange and having its bottom inclined upward from said space, and a side wall extending upward from said bottom Wall; of a separable cover member comprising a top wall resting on the side wall of the body member and having spaced openings, one of which is arranged above the space within the depending flange of the body member, and also havin a longitudi-- nal depending grooved portion extending outwardly from the other opening and a depending marginal flange surrounding the side wall of the body member and further having a depending flange inclosing the said spaced openings; said flange bearing on the bottom wall of the body member and inclosing the space within the dependingflange and the longitudinal channel-portion thereof and forming, in conjunction with the side wall of said body member an air space, substantially as and for the purpose set forth.

In testimony whereof I have hereunto setmy hand in presence of two subscribing witnesses.

WALTER E. FROST.
